BERNIE ECCLESTONE said the United States Grand Prix is on the brink of being axed from next year’s calendar.

It was believed Tavo Hellmund’s Full Throttle Productions owned the rights to host the race but Ecclestone has revealed the contract with Hellmund was recently cancelled after he was found to be in breach.

Asked if the USGP was in danger of being dropped Ecclestone said: “Yes, it will be, for sure, 100%.”
